Method Detail

getDefaultController

public static CodeEditorController getDefaultController()

Get the default singleton controller.

Returns:

the default controller

checkCommandsAfterNavigation

public void checkCommandsAfterNavigation(Context context)

Utility routine which is used to verify command sensitivity after a change in the caret position of the editor.

Parameters:

context - the current context

getCodeEditorFromContext

public static final CodeEditor getCodeEditorFromContext(Context context)

Utility routine to fetch the CodeEditor instance from the context. If a code editor (or gutter) is not the active view, then this will return null.

Parameters:

context - the current context

Returns:

the code editor instance, if any

getEditorPaneFromContext

public static final BasicEditorPane getEditorPaneFromContext(Context context)

Utility routine to fetch the BasicEditorPane instance from the context. If a code editor (or gutter) is not the active view, then this will return null.

Parameters:

context - the current context

Returns:

the editor pane, if any

update

public boolean update(IdeAction action,
                      Context context)

This method is called when the availability of a specific command needs to be determined. For example, it may be called when the user clicks on a menu, or perhaps to update the "enabled" state of toolbar actions. Call the action's setEnabled() method to set the appropriate command sensitivity.

Specified by:

update in interface Controller

Parameters:

action - the action associated with this command

context - the current context

Returns:

true if the controller handles the specified command.

handleEvent

public boolean handleEvent(IdeAction action,
                           Context context)

This method is called when a user interaction with a View triggers the execution of a command.

Specified by:

handleEvent in interface Controller

Parameters:

action - action whose command is to be executed.

Returns:

true if the controller handles the specified command.

menuWillShow

public void menuWillShow(ContextMenu popup)

Called just before the context menu is popping up.

Specified by:

menuWillShow in interface ContextMenuListener

Parameters:

popup - the current view context menu

menuWillHide

public void menuWillHide(ContextMenu popup)

Description copied from interface: ContextMenuListener

This method is called just before a showing context menu is dismissed. Most implementations should not do anything in this method. In particular, it is not necessary to clean out menu items or submenus that were added during ContextMenuListener.menuWillShow(oracle.ide.controller.ContextMenu), since the IDE takes care of that automatically.

Specified by:

menuWillHide in interface ContextMenuListener

Parameters:

popup - the context menu being hidden

handleDefaultAction

public boolean handleDefaultAction(Context context)

Called when the user double clicks on an item that has a popup menu. Only one listener should return true from this menu.

Specified by:

handleDefaultAction in interface ContextMenuListener

Parameters:

context - the current context
